The Book of Lost Names by Kristin Harmel
This historical fiction novel is based on a true story. The timeline, which flips back and forth between WWII and 60 years later, follows the life of Eva Traube. She is a young Jewish woman living in Paris France, fleeing from the Nazis and then becoming a forger of papers to help others flee and cross the border into Switzerland. The older Eva is now a semi-retired librarian, who comes across a story in the newspaper about a book, saved from Nazi destruction, that contains a secret code which represents the true identities of the adults and children she helped to save. The story is one of bravery and resilience in the face of horrific danger.
